One of the things I am paranoid about is running out of fuel, as my boat drinks fuel. Not so much getting stuck, but I hear stories about it hurting engines. This last summer at Havasu I was cruising around the island back to the Nautical, maybe 40-45mph and my port engine quit. I was on fumes so I assumed I finally ran out. Got back to the dock on the other running side, and the port motor fired right back up and idled nicely.
When can you hurt them ruining out of fuel? WFO? just cruising? depends?

When I accidentally ran mine out of fuel it threw an alarm and I had to take it to Mario to get it cleared

The hurt comes from them going lean as they begin to starve themselves of fuel. In my experience in 2 strokes, the shit hits the fan when you are running it hard, and it runs out this causing a lean condition.

Common sense I would think that too.

Never a good idea, will hurt your motor every time you do it, how much is up to your motor.

2 strokes its really bad as the engine oil is mixed with the gas. So you also loose oiling. If idling I haven't had an issue but if under a load it can seize things.

As mentioned running a two stroke out of fuel is never a good thing. Running one out of fuel at high rpm is usually catastrophic. That said I had the fuel pump switch shut off three times during last years enduro running over 7500 without issue. Pulled the heads at post race inspection and the cylinder walls looked fine, no scuffing. Things that make you go huh.

Once you use up a two strokes crankcase saturation nothing good comes out of it.

Yeah.... mine runs out ALL the time. My fuel gauges don't work, and haven't for years. Same with my uncle in his. Our old 2.4 carbed engines are just fine.

Yea I run mine out everytime I run it.... that’s the only way I know I’m at half tank and switch it over to the other tank 😂
